a full, clear, and exact description of the insuch as will enable others skilled Venden,

tol make and inthe Aart to which appertains use the same.

VThis invention relates lto attachments for .internal combustien engines and the primary object of the invention is toprovide an improved means for effectively heating lthe intake manifold, and thereby'vaporize the fuel and break the same into small particles.

Another object of the invention is to provide an improved attachment for internal combustion engines which can be quickly and readily secured in place, which will effectively utili-Ze the vheat from the exhaust manifold to heat the intake manifold.

Another object of thisinvention is to provide an attachment for internal combustion engines formed of heat conducting material which is adapted to be positioned intermediate the exhaust and intake manifold and in contact therewith, so as to permit the heat from the exhaust to be utilized for heating the intake manifold.

A still further object of the invention is to provide a detachable attachment for automobiles which is of heat conducting material, so constructed, that the same can be heated prior to the positioning of the same on the intake pipe of the motor, thereby facilitating the starting of the engine during cold weather.

A still further object of the invention is to provide an improved device of the above character, which is durable and efficient in use, one that is simple and easy to manufacture, and one that can be placed upon the market at a reasonable cost.

With these and other objects in view the invention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described, claimed and illustrated in the accompanying drawings, forming a part thereof in which:

Figure l is a side elevation of the Ford motor with the improved attachment applied thereto.

Figure 2 is a central vertical section taken through the device showing the same applied to a motor, and

Figure 3 is a detail perspective view of the attachment removed from the motor.

Figure 4; is a detail perspective view of the clamping means for the attachment, removed.

Referring to the drawings in detail, wherein similar referencecharacters designate corresponding parts throughout the several views, in which the numeral l generally indicates the improved devicewhichis adapted to be applied to ann internal combustion engine 2, which is ofthe ordinary Ford or other preferred type. The engine 2 includes Xhaust manifold 3 having the outlet pipes et connecting with the outlet ports of the intermediate cylinders, and the intake manifold 5.

in ordinary type of internal combustion engine has the intake manifold located below the exhaust manifold and in spaced relation thereto and the improved device 1 is adapted to fit and rest upon the top of the intake manifold' and extend upwardly therefrom into vengagement with the intake pipe. rilhe sides and the upper surfaces of the attachment are arranged to engage the eX- haust manifold and the intermediate pipes 4 leading from the outlet ports for the intermediate cylinders.

rlhe improved attachment l is preferably formed of cast iron, but it is to be understood that the same may be formed of any heat conducting material and comprises a solid body 6 having a right angle extending arm 7 formed on the upper terminals thereof. The inner surface of the body 6 inclines downwardly and outwardly as at 8, to conform to the configuration of the intake pipe while the sides of the arm 7 are curved inwardly as at 9 to conform to the configuration of the exhaust manifold. lit will be seen that the device is so shaped to snugly fit between the exhaust and intake manifold and thus becomes heated from the exhaust manifold and in turn heats the intake manifold at the turn thereof so that as the fuel is drawn up through the intake pipe the same comes in contact with the hot portion of the intake manifold and becomes vaporized and broken into small particles. While the arm 7 serves to prevent turning of the attachment l, ll have provided for bolt 13 which has a turned orhook end 1/1 for engagement around another one of the clamps 12 located at the opposite side of the solid body 6. A thumb nut 15 is threaded upon the outer face of the bar 10 at this end to cause the latter to securely clamp the attachn'ient 1 in proper position.

From the foregoing, it v'vill be seen that the device is so constructed that the attachment 1 may be readily placed in position and securely clamped, or released and re moved, when desired. This isan important feature, as during extremely cold Weather it is often necessary to provide means for heating the intake manifold prior to starting` the engine. When it is desired to heat the manifold prior to starting` the engine it from its position and heat the same on a stove or the like and then place the same back in. position.. This will effectively heat the manifold and facilitate the starting of the engine.l

From the 'foregoing description it can be seen that an improved device is provided which is of exceedingly simple and durable character, and which can be readily and is merely necessary to remove the device quickly fitted to Ford motors for heating the intake manifold thereof. y

ln practice, l have found that the form of Amy invention illustrated in the accompany-v ing drawings and 'referred to in the above description, as the preferred embodiment, is the most efficient and practical; yet realizing the conditions concurrent With the adoption of my device will necesarily vary, l desire to emphasize the fact that various minor changes in details of construction, 4proportion and arrangement of parts may be re-l sorted to, when required, Without sacrificlng any of `the advantages ofmy invention` asl set forth.` p y v lV hat is claimed `as nevv'is:

ln combination with an exhaust pipe havingy dependingv portions spaced from each other, a fuel supply -pipe bridging said p0rtions, and securing clamps for one of said pipes, ai heat conducting member having an extension disposed in said space 'and in contactvvith both pipes, an extension on said ymember in contact With one side ofl the fuel supply pipe, a securing bar for the member having` a hook at one end integral therewith to engage one of the clamps and a hook to engage the other clamp adjustably'mounted adjacent they other end of the bar.

ln testimony whereof l aflix my signa ture in presence of two Witnesses'.v

WILLIAM J. FYAN.
